Aubrey McClendon, one of the pioneers of the U.S. shale boom, was indicted by a federal grand jury Tuesday on charges of conspiring with an unnamed company to rig the price of oil and gas leases in Oklahoma.

The indictment alleged that Mr. McClendon orchestrated a campaign to keep bid prices down from 2007 to 2012, while he was chief executive of Chesapeake Energy Corp., amid a land-leasing boom across the U.S. The Justice Department didn’t name anyone else it believed participated in the alleged conspiracy.
